How well can the network see Bethlehem?

The nearest Doppler radar is KOKX (New York City, NY), 56 miles to the SSE. A WSR-88D's lowest routine scan sits half a degree above horizontal, and the earth curves away beneath it, so by the time that beam reaches Bethlehem its centre is about 4,200 ft above ground. That is far enough out that the beam has climbed above the lowest few thousand feet. Storm structure aloft is visible; a shallow circulation near the ground may not be, and a warning here can arrive before anything looks dramatic on the radar picture.

The closest instrument actually measuring the air is KOXC · Oxford Arpt on the ASOS/AWOS network, 12 miles away. Near enough to be representative on most days, though a summer thunderstorm can soak one and miss the other entirely.

Beam height is the standard 4/3-earth approximation for the 0.5° scan and assumes normal refraction; it is where the centre of the beam is, not its edges, and unusual temperature profiles bend it. Radar siting from the NWS WSR-88D network, station positions from the Connecticut observing network as of this build.
